hello
i have just two questions about the pocket piano
im having just a little bit of trouble with the schematic
i don't know where to connect the two capacitors located near the multiplexer chips (vcc and grd)
(are they connected to pins on the capacitors or to the arduino)
there is also one located near the mcp 4921 chip

and secondly
where the sting of three potentiometers there is a vcc out and a pot 1
(i am wondering if that pot 1 is a typo and is suppose to be a GRD)

To the power and ground as close to the pins on the multiplexer chip as you can get.

Never heard of a sting, do you mean a wiper?
These go to the first three analogue inputs of the arduino A0, A1 and A2

He probably meant "the string of three potentiometers".
